I switch my Futaba 6EXA & 4VF Xmtr xtls back & forth (ch 36, 38, 40, 41 & 48) betweem Xmtrs without any problems. They are all Futaba Xtls. Like in the UK, it is legal to do so in Canada. I have had no loss of range, or any interference problems with my radios, or caused any problems with other pilot's radios.
